Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a high-efficiency heat dissipation device. Background Art

[0002] Transformers are essential electronic components that convert AC voltage, current, and impedance. They are ubiquitous in everyday life, but they still have some flaws and shortcomings. Specifically, they require improvement: 1. Transformers typically have fixed cooling fins at the front and back ends. This accelerates heat dissipation by utilizing the faster heat conduction of metal and increasing the contact area with the air. However, transformers are typically used outdoors, and dust accumulates on the cooling fins after a period of use, reducing their contact area with the air. 2. Transformers are typically mounted in mid-air, making the lower mounting area weak. Furthermore, the transformer's heavy weight can lead to unstable installation. Therefore, we propose a transformer with a highly efficient heat dissipation device. Utility Model Content
